I’m shocked and saddened to read this. I always enjoyed all of my interactions with him. Paul

The KW helmet is a rear seam manganese rim McCord and lot code is 1162A. This puts it in the mix from Front to rear seam. The front seam is McCord 10_9 A. This puts it early in the manganese front rim lots.

WalkaHeap I’m very interested. What would you want for it? And how would you like to be paid?  Thanks. 

Be mindful. The McCord and Schlueter heat lot codes are not the same.

Yah, the gutter was the giveaway to me, it was likely heavily sharpened and the tip was cut down a bit trying to keep the same type of shape though.

This original art (from above link) had the following on the reverse. Not sure when it was added. Wanted to keep images on the forum. 

I actually have an original model 1872 crossed saber insignia. No company/troop letter or numeric designation, just the sabers. If you’re interested, let me know. 

I think I've found a match (at least the only one that I could locate in the records). I believe your man to be Dominick G. Pennella (1923-2008), and, according to his obituary, he was an "Army Medic with the 28th Division in the Normandy and Ardennes-Alsace Campaigns." His name can be found in that same record as Alfred Clever.   No problem!

I could be jumping the gun on the headband and nape being being repro? Could have been installed and hardly worn... hit by a bullet and put up? All guesses of course. I zoomed in on the image of the scrape on the liner. From the one pic... I dont see any signs of sand paper or filing....  

The gutter is about the right length for a Ka-Bar.  The handle is also about the right length, but curved down some.
